Now the toxicology reports have been released, with his widow Beth issuing a statement to let fans know.

She says in a Facebook post: “Toxicology results are back as is the official cause of my husband's death. Cause of death – drowning.

“Toxicology: Oli was apparently self-treating for manic-depression that has run in his family for several generations. Anti-depressants were found in his system, as well as a sleep aid.

“The psych meds found in his system were the same ones that a close relative has been prescribed for a long time, so he knew what to hunt down for the ‘treatment'.

“Seeing how he was not going – and wouldn’t go – to a doctor to get diagnosed with the issue and was not being prescribed the medications and monitored on them, it explains his occasional erratic behaviour here at home.”
